VIR_ALLOC and vshMalloc (and similar methods for calloc, etc), seem to be roughly identical in function, with the only difference being that VIR_ALLOC and friends are used in libvirt proper, whereas vshMalloc and friends are used in the virsh code.  Is there a reason why virsh does not simply use VIR_ALLOC and friends?

vshMalloc calls exit() on failure, VIR_ALLOC returns NULL to the caller.
 libvirt.so (anything in src/) cannot call exit, but virsh is an
executable not a library, so exiting is sometimes easier than dealing
with failed allocations.
